Synthesis of bio-based methylcyclopentadiene via direct hydrodeoxygenation of 3-methylcyclopent-2-enone derived from cellulose.

文献摘要

能源和环境问题促使人们探索将可再生生物质转化为燃料和高附加值化学品的高效工艺。在此,我们描述了一种利用纤维素生产甲基环戊二烯(MCPD)的创新路线,包括将纤维素转化为3-甲基环戊-2-烯酮(MCP)以及随后在氧化锌钼催化剂上选择性加氢脱氧成MCPD。锌钼氧化物催化剂的优异性能归因于在氧化锌还原过程中生成了ZnMoO3物种。实验表明,在MCP的气相加氢脱氧反应中,ZnMoO3位与C=O键而不是C=C键的优先相互作用导致了MCPD的高选择性生成(碳产率为70%)。


The exploration of highly efficient processes to convert renewable biomass to fuels and value-added chemicals is stimulated by the energy and environment problems. Herein, we describe an innovative route for the production of methylcyclopentadiene (MCPD) with cellulose, involving the transformation of cellulose into 3-methylcyclopent-2-enone (MCP) and subsequent selective hydrodeoxygenation to MCPD over a zinc-molybdenum oxide catalyst. The excellent performance of the zinc-molybdenum oxide catalyst is attributed to the formation of ZnMoO3 species during the reduction of ZnMoO4. Experiments reveal that preferential interaction of ZnMoO3 sites with the C=O bond instead of C=C bond in vapor-phase hydrodeoxygenation of MCP leads to highly selective formations of MCPD (with a carbon yield of 70%).
